(PTO-J05) Integrated Spring Extension Assist Mechanism

Be the First to Review
  • Recommendation:
    For trans-femoral amputees
    With lower functional levels
  • Medium stance phase stability
    Suitable also for hip disarticulating amputees
    Not Suitable for amputees with higher functional levels
  • Description:
    Upper and lower joint section is connected with linkage bars. The stance phase stability is achieved with the polycentric kinematic (adjustment of the instant center of rotation by adjustment of the stop). The step-less adjustment of the axis friction and of the extension assist spring controls the swing phase.
    Technical Data:
    Knee flexion range: approx 120 Degree
    Height (knee axis center- upper edge): 37 mm
